COMMlNUTlNG-MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 470,395, dated March 8,1892. Application filed October 31, 1891. Serial No- 4=10,474-. (N0model.)

i To all whom it may concern.-

Be it known that I, HENRY A. HANNUM, of Oazenovia, in the county ofMadison, in the State of New York, have invented new and usefulImprovements in Comminuting-Machines, of which the following, taken inconnection with the accompanying drawings,-is a full, clear, and exactdescription;

This invention relates to a comminuting machine designed, chiefly, forcutting up green bones for chicken-feed, but also adapted for crackingcorn, slicing vegetables, and reducing other substances to fineparticles; and the invention consists in a novel construction andcombination of its component parts, constituting a comminuting-machineof great efficiency and convenience in its operation,

as hereinafter fully described, and specifically set forth in theclaims.

In the annexed drawings, Figure l is a side elevation of a machineembodying myinvention. Fig. 2 is a vertical transverse section. Fig. 3is a top plan view with the yoke and follower removed. Fig. 4C is anenlarged vertical transverse section of the base of the hopper andadjacent parts. Fig. 5 is an enlarged detached side view of thecutter-head, viewed from the smaller side thereof; and Fig. 6 is a viewof a section of the larger side of the cutter-head, a portion thereofbeing broken away to show the attachment of the cutter.

Similar letters of reference indicate corresponding parts.

A represents the supporting-frame of the machine, which frame may be ofany suitable shape and formed of metal. It has rigidly attached to it orintegral with it an annular raised portion B, which constitutes the bottom of the hopper B, said bottom being thus convex on its top. Throughthis bottom is a slot 1), extending radially from one side part wayacross the same, as clearly seen in Figs. 2 and 3 of the drawings.Beneath the bottom 13 is a horizontal shaft e, disposed at one side ofthe axis of the hopper and crosswise of the :slot 1) and journaled insuitable bearings I I --'on the frame A. To this shaft is firmly securedthe annular cutter-head H, the periphery of which protrudes through' theslot 1).

The peripheral face of this cutter-head is beveled to one side, so thatthe lower side along one side of the respective slots and se cured ingrooves in the cutter-head at the ends of the slots, as shown in Figs. 5and 6 of the drawings.

In order to obtain ample clearance for the fragments of bones notsuffieiently reduced to pass through the slots 12, I widen the slots a atoward the high side of the cutter-head and provide said side of thecutter-head with clearing-notches a a, so that such coarse fragments ofbone cannot clog in front of the cutter, but slide along the edge of theslots and through the clearing-notches a and into the hopper, and areagain brought around to be acted on by the cutters. The cutter-head maybe rotated either by a hand-wheel L or a pulley or gear attached to oneend of the shaft 6. Upon the hopper-bottom is mounted revolubly thehopper 13', preferably by providing the former with an annular rib r,inside of which the outer bottom edge of the hopper is fitted, so as toallow the hopper to turn, as best seen in Fig. 4 of the drawings. Thehopper is retained in its seat on the bottom B by means of plates P P,secured to posts P P on the frame A and bearing 011 shoulders on theexterior of the hopper above the rack f, which is attached to the baseof the hopper B. i i

To the frame A is pivoted a lever g, and to the lever, at opposite sidesof the fulcrum thereof, are connected two pawls Z Z, which engage therack f. A pitman t' connects the said lever to a crank 71, secured tothe shaft e, and thus the. lever 9 receives an oscillatory motion,which, by means of the pawls ZZ',imparts an intermittent rotary motionto the hopper B. By throwing one of said pawls off from the rack f, soas to retain it out of engagement therewith, the speed of the revolutionof the hopper B can be reduced half when desired, which may be requiredin comminuting very hard substances.

At opposite sides of the'h'opper B are two standards T T, rigidlysecured to the frame A and extending above the top of the hopper. A yokeor cross-bar Y is pivoted at one end to one of the standards andremovably connected at the opposite to the other standard, preferably bya notch 'v in the side of the yoke, which notch allows the yoke to beslipped sidewise onto the standard, and a nut 11' on the standard overthe yoke prevents the latter from being'forced upward and off from thestandard. Central over the hopper B the yoke Y is formed with a half-nutt, and to the side-0f the yoke is hinged a strap 73', formed with asimilar half-nut, so that by laying said strap closely against the sideof the yoke a complete nut is formed. The strap is retained in saidposition by a pin 10, passing through perforated ears on the strap andyoke. In the hopper B is a vertically-movable follower 0, to the centerof the top of which is firmly attached an upright feed-screw D, whichworks in the aforesaid nut on the yoke Y. To compel the follower andfeed-screw to turn with the hopper, I connect said hopper with thefollower by a vertical tongue 3 on one entering a groove in the other.

In operating the described machine the strap 15' is to be swung aside toseparate the nut on the yoke, as indicated by dotted lines. in Fig. 3 ofthe drawings. Then the yoke is to be swung on its pivot to carry it toone side and away from over the top of the hopper. Then the follower Ois to be withdrawn from the hopper. The bones or other substance to becut up or comminuted are then introduced into the hopper, the followerreplaced over said substance, the yoke Y swung back over the hopper andsecured to the standard, and the strap 25' placed across the screw D andfastened to the yoke. Then by turningthe shaft e the cutter-head II isrotated, and at' the same time-the hopper B, with the follower O andfeed-screw D, receiv'es intermittentrotary motion, and by the turning ofsaid screw the follower is caused to press the bones against the cuttersc c as rapidly as they are reduced. Inthis comminut-ing operation mymachine is rendered very effective by the arrangement of the cutter-headat one side of the center of the convex hopper-bottom and the protrusionof the beveled cutter-head to a point above the apex of the said bottom.

In the operation of the machine the bones are carried successivelyacross the cutterhead from the lower to the higher side thereof, and bythe projection of said higher side above the surface of the stationaryhopperbottom B a'space is produced directly over at the rear portion ofthe said bottom, and thus the bones are allowed to be carried freely tothe cutter-head from the lower side thereof and the pressure of thefollower is directly over the cutter-head.

To clear the cutter-head of the cut substances passing through the slotsof the cutter-head, I attach to the under side of the frame A a scraperV, which stands closely to the innerside of the cutter-head, as shown inFig. 4 of the drawings.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is
